- I Application filed September 7,1926. Serial No;'133,989.

Experience has taught those skilled in this art that theweakness of the present style tile drain is the relatively short length of the tile. When the tile is laid in sandy soil the water in its course through .thedrain drops through the cracks: or joints of the drain and causes thesand to wash out from under thetile and forms a basin under the samejtheytile eventually drops into this basin and/the drain is ruined. The important-objectof my-invent-ion is to eliminate these defects by making a continuous bottom or one constructedsolid with a sectional top.

, Another very important object of my in- 4 vention lies in the provision of moulds which allow the tile sections to be formed while the ditch is being dugwhereby the sections may be made asneeded and cemented together so novel features of construction,

as toform practically a one-piece or integral drain structure'.- 1 r A Another very important object of the m-j vent-ion lies in the provislon of a form which consists of few parts of very simple construction which-maybe easily and quickly assembled and disassembled.

A still further very important 'object'of the invention lies in theprovision'of moulds which are inexpensive to manufacture,-

will be hereinafter more fully described and claimed.

Referring to the drawings in detail it will be seen that. thetop: form illustrated to ad vantagein Figs. '1 and '3 includes a pairof end members '5 and-side rails 6. The end members 5 are fof semi-circular formation being provided on their outer edges with notches 7 for receiving reinforcing rodsand on their ends with notches 8 which are disposed also in the outer edges for the reception of the side rails 6. In using this top mould the ditch into which the drain is to be disposed; is partially dug semi-cylindrical andthe form is set therein and the concrete poured in the form to form asemi-cylindrical: section indicated at 10 in Figs. 5 and 6 and-the siderails 6 will cause the formation of the grooves. 11 at-the side edges of the section. The sections will be removed from the ditch after the concrete has properly set. The ditch is then dug the desired depth and r the bottom section formed therein by using the moulds shown in Figs. 2 and 4. This bottom mould includes end members 12 and side rails 6. The end members 12 are provided with the notches 14 similar to notches 7 and: notches 15 at their ends and at the inner edges for receiving the rails 6. When the end membersand side rails are assembled the concrete is poured in the form and will produce a section 16, the side rails forming the grooves 17 so that a tongue and groove connection is provided between the side edges of the top and bottom sections. After the bottom sections are properly set the top sections will be placed thereon as clearly indicated in Fig. 6 and the length may be cemented together as is indicated at 18. In Figs. 8 and 9 I have shown another embodiment of the side rails. This rail is indicated by the numeral 19 and is of an elongated tubular construction of substantial square cross sections having a ridge 20 extending. from one corner longitudinally thereof and t co-planar with one face and on said face and ridge there are disposed suitable indicia 21. This embodiment oi the side rail is light in construction and enables the drain sections to he made in different lengths as will bviouslv be desirable In Figs. and. 11 an embodiment of the end members has been shown denoted by the numeral 22- and having outer edge notches 23 and provided With detachable end plates 24 held in place by bolts These plates are of arc-uate 'lormation and their inner edges have projecting therefrom la s 26 on which the rails G or 19 may rest. In Figs. 13 and 14- substantially the same embodiment shown except that the plates it are provided either with note-hes 2? or projections 28 for forming a tongue and groove. connection between the top and bottom sections formed by the bowl. In Fig. 112 an interseel irni has been illustrated provided with openings 30 through which may be extended reinforcing: rods and provided with suitable end notches 31 forreeei ving end rails 6 or 1 9. In Fig. 17 an embodiment of the :end member indicated at 32 and provided with a rod 34: em tending there'froin and prl'ijeetinn beyond the ends to form dowel pins.

It is" thought that the eonstruetion. utility and advantages of this invention will now be apparent to those skilled in this art without the necessity of a more detailed description thereof. The present embodiments of the invention have been disclosed in detail merely by way of examples since in actual practice they have attained the features of advantageenumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction may be resorted to without departing from the spirit or scope of the invention as hereinarl ter claimed or sacrificing any of its adrantapges.

Having thus described my invention, what I claim as new is:

1. A. form of the class described, includ ing a pair of semicircular end members having, notches at their extremities and a pair of side rails restahle in said notches.

A form of the class described. including a pair of semi-eirenlar end members, a pair of side rails, and means onthe extremities of the end members for receiving the side rails.

23. A "torun ot' the class described, ineluding a pair (:15 semi-eir a1lar end members, a pair oil. side rails and means on the extren'iities of the end members torreceiving the side rails. said means including structures for forming tongue and grooves.

t. A :t'ortn of the rlass described. including. in; comhinatiom a pair of semi-oircular end members. a. pair of side rails, ineansttor resting: the side rails on the end inen'ibers, said side rails being of a square tubular formation having a. Tit ge along one corner hnip itlulinally thereof (:O-Plitllill with 2. said one face and. ridge being pro.-

1 a l with measuring indieiar It form, of the class desrribed. including a pair of semi-circular end members, areuaize plates detachably engaged on the ends oi the end members and tormed with ii'nrardl v extend iinr lugs and. a pair of side rails rest-able on said lugs.
